used to do 过去常常做某事be used to doing 习惯于做某事be used to do sth被用来做某事1. used to的一般疑问句有两种构成方法:1)将used提前至句首,结构为:Used + 主语+ to do sth...? 2)将did提前至句首,结构为:Did + 主语+ use to do sth...? 例如:Used he to get up early? = Did he use to get up early? 2. used to的反义疑问句有两种构成方法,例如:1)He used to smoke,didn't he?2)They usedn't to like opera,did they? 3. 同样,其否定句也有两种构成方式:1)直接在used后面加上not,也可一起缩写成usedn't. 结构为:主语+ used not to do sth... 或主语+ usedn't to do sth... 2)借助于助动词didn't,其结构为:主语+ didn't use to do sth.... 例如:He used not to get up early. = Heusedn't to get up early. = He didn't use to get up early. 4、be(get,become)used to结构在意义上相当于accustomed to “习惯于”,从形态上看,used是个分词型形容词,to是介词,因此后面只能跟名词、代词或动名词。例如:1)They got used to living in the countryside.他们已习惯于住在农村。2)I've got used to being a vegetarian.我已经习惯吃素食。3)He is used to hard work.他习惯于艰苦工作。5、be used to表示“习惯于某事”的状态,而get used to则表示由“不习惯”到“习惯于”这一动态的过程,意思是:“(变得)习惯于”;“开始习惯于”。试比较:He was used to the cold weather after he lived there for two years.在那里住两年后,他已习惯了寒冷的天气。I think it is a bit difficult for you to get used to the humid weather here.我想,让你习惯于这里潮湿而炎热的天气有点困难。You'll soon get used to living in the country.很快你就会习惯于住在乡下了。6、当主语是物的时候是指被用来做某事,be used to是动词use的被动语态,在这种结构里,to是不定式符号。例如: A metal bar was used to force the door open.用金属棒把门撬开。The threshing ground was used to hold a mass meeting.打谷场曾用于举行群众大会。
